Definitions

  • the present invention relates to a tire structure having a flexible plastic valve whose passage can be sealed by the pressure form the sidewall of the tire.
  • a conventional tire for scooters or strollers is shown in FIG. 5 and generally includes a solid tire engaged with a wheel rim 11 .
  • the solid tire is generally made from EVA or PU.
  • PU has better flexibility and is easily steered, the material tends to be deformed permanently and therefore is disengaged from the ring 11 . It is too stiff for the EVA and tends to be worn out so that the EVA tire cannot be satisfied by the customers. If the tire is made from rubber which is too heavy. Therefore, the small tires used on scooters or strollers need inflatable tires.
  • the conventional inflatable tires involve more parts and are expensive which is the last factor that the tires need.
  • the present invention intends to provide a inflatable tire structure that has a flexible valve extending through the sidewall of the tire and the valve is sealed by the pressure of the sidewall.
  • a tire structure comprising a hole defined through a sidewall of the tire and a flexible valve is inserted in the hole.
  • a first passage is defined longitudinally through the flexible valve. The flexible valve is deformed by the sidewall so as to seal the first passage.
  • the primary object of the present invention is to provide a tire that has a flexible valve which can be squeezed by the sidewall of the tire to seal the passage in the valve.
  • FIG. 1 is a cross sectional view to show a tire structure of the present invention
  • FIG. 2 is a cross sectional view to show an inflation needle inserted in the passage of the flexible valve as shown in FIG. 1;
  • FIG. 3 is a cross sectional view to show another embodiment of the flexible valve engaged with the sidewall of the tire of the present invention
  • FIG. 4 is a cross sectional view to show an inflation needle inserted in the passage of the flexible valve as shown in FIG. 3;
  • FIG. 4 is a cross sectional view to show another embodiment of the flexible valve engaged with the sidewall of the tire structure of the present invention.
  • FIG. 5 is a perspective view to show a conventional solid tire.
  • the tire structure of the present invention is engaged with a wheel rim 30 and comprises a hole 22 defined through a sidewall 200 of the tire 20 and a flexible valve 40 is inserted in the hole 22 .
  • a flange 400 extends from radially outward from the flexible valve 40 and is engaged with an inner periphery of the tire 20 so that the flexible valve 40 will not be disengaged from the tire 20 .
  • a first passage 42 is defined longitudinally through the flexible valve 40 and the flexible valve 40 is deformed by a pressure of the sidewall 200 from a periphery defining the hole 22 as to seal the first passage 42 .
  • FIGS. 3 and 4 show another embodiment of the present invention wherein an extension portion 401 extends from the flange 400 and a second passage 43 is defined radially in the extension portion 401 of the flexible valve 40 .
  • the second passage 43 communicates with the first passage 42 .
